Finally got around to looking at DVD for this effect. The actual prop and gimmick seem to be well
done. However the DVD, as a mechanism to learn this trick, is not well prepared and is confusing.
This is going to take me longer to sort through the DVD content in order to obtain what I need to
competently perform this trick. Maybe instead of having the two magicians detail how each performed
this the DVD material would have been better served with only one describing the procedure. Also
eliminate some of the sidebar discussions that I don't feel are relevant to learning how to perform
this routine.
